Well it looks like US is not an option anymore.

Canada on the other hand gives you PR on entry if you're skilled enough.

Money doesn't matter if it becomes an eternal struggle or impossible to maintain legal status.

One have to put things in prerspective. It took 40-50 years for the silicon valley to become what is is today. Once there are enough tech presence in Canada, tech situation would improve. There would be ample amount of tech folks, and new innovations would come along. New companies would be founded and things would be at par, or even better. Anyhow I see, US heading towards political turmoil/instability.

A lot of immigrants want career opportunities, a reasonable path to permanent residence and/or citizenship, and a good environment for their family.

#1 could change, some tech companies have started to realize they can offer more remote jobs and save money while offering salaries that are still very competitive to anyone not living in the Bay Area. #2 was already problematic before Trump. #3 is often better outside the US.

That makes Canada even more attractive to tech companies because they can save money. Canadian salaries and living standards are still better than many other countries'.
